Abstract:The standard ΛCDM model of cosmology is formulated as a simple modified gravity coupled to a single scalar field ("darkon") possessing a non-trivial hidden nonlinear Noether symmetry. The main ingredient in the construction is the use of the formalism of non-Riemannian spacetime volumeelements. The associated Noether conserved current produces stress-energy tensor consisting of two additive parts -dynamically generated dark energy and dark matter components non-interacting among themselves. Noether symmetry br… Show more
